Support Publish or Perish
The development of the Publish or Perish software is a volunteering effort that has been ongoing since 2006. Download and use of Publish or Perish is and will remain free (gratis), but your support toward the costs of hosting, bandwidth, and software development are appreciated. Your support helps further development of Publish or Perish for new data sources and additional features.
This is a very tricky problem. Even commercial databases like Thomson Reuters Web of Science (ISI) have problems with this, see:
- Harzing, A.W. (2016) Health warning: Might contain multiple personalities. The problem of homonyms in Thomson Reuters Essential Science Indicators, Scientometrics, vol. 105, no. 3, pp. 2259-2270. Available online...
Please also remember that PoP results are based on Google Scholar, Microsoft Academic, and other data sources and not a manually curated bibliometric database with a very high subscription fee, such as Scopus or the Web of Science.
However, there is a lot you can do to get the right author by "smart searching". Have a look at the Publish or Perish tutorial which has lots of tips and tricks. In particular, read the pages on author disambiguation.
Many longstanding users are asking to reinstate the subject/discipline categories. Removing them was certainly not by choice; Google Scholar abolished them in 2012; they claim they were not used by most users. For more information on this:
Please remember PoP is an interface to Google Scholar (and, since PoP version 5 and 6, Google Scholar Profiles, Microsoft Academic, Crossref, Scopus and Web of Science). We do not sit up at night entering your publications in a "Harzing database" as some users seem to think :-).
Google Scholar's and Microsoft Academic's processing is automatic (unlike Scopus and Web of Science which are manually curated databases, with the associated price tag) and hence occasional errors do occur. For more information limitations of Google Scholar, see the Google Scholar pages in the PoP tutorial.
We have no influence on how Google Scholar or Microsoft Academic parse their data, so you will need to contact them for any problems with your publications or citations. For more information, see the Accuracy page of the Publish or Perish manual.
Again, please remember PoP is an interface to Google Scholar and other data sources. We have absolutely no interest in blocking your use of Publish or Perish. However, Google Scholar insists on asking you to verify you are a human, not a robot, if you do regular searches. For more information see: Google Scholar: Captchas.
Please note: Google Scholar Profile searches are not subject to the same captcha requests; The other four data sources in PoP do not display these limitations either.
- Provided you use exactly the same search syntax in both, your h-index in PoP and GS will identical (see Accuracy: PoP vs GS).
- The Web of Science (ISI), Scopus, Google Scholar and Microsoft Academic have different levels of coverage for different disciplines. For a comprehensive comparison, please see: Microsoft Academic: is the Phoenix getting wings?
For detailed information see also:
- Harzing, A.W.; Alakangas, S. (2016) Google Scholar, Scopus and the Web of Science: A longitudinal and cross-disciplinary comparison, Scientometrics, vol. 106, no. 2, pp. 787-804. Available online... - Publisher's version - Presentation slides - Video presentation of this article.
Update to the latest version of Publish or Perish. From PoP version 6.17 and later, Publish or Perish includes results from Microsoft Academic Knowledge API in Azure Cognitive Services, made possible with a generous grant from Microsoft Research. You no longer need a subscription key, although you can use your own key if preferred in the Microsoft Academic preferences dialog.
This may occur in Publish or Perish version 5.x if you are still using Windows XP. You will typically see a dialog box similar to the following:
The underlying cause of the error message is a mismatch between the SSL certificate that Publish or Perish expects for its connection to Google Scholar and the actual certificate provided by Google Scholar's server.
It appears that Google sends an SSL certificate for www.google.com instead of scholar.google.com or *.google.com for requests that originate from older versions of Internet Explorer (such as IE8 that Publish or Perish uses on Windows XP, because no later versions than Internet Explorer 8 are available for Windows XP).
A more sinister potential cause is that you are using a web proxy (perhaps your organisation's) and that its SSL certificates are invalid or even compromised, or that you are using an anti-virus tool or similar security program that actively intercepts HTTPS connections and offers its own SSL certificates.
There are several (partial) solutions to this issue, depending on the exact cause. You will have to try them each until you find one that works.
Before you start, make sure that you are using Publish or Perish 5.27 or later. We have added some automatic mitigations for the certificate problems in this version of Publish or Perish.
- Simply click "Yes" when asked if you want to proceed. This doesn't solve anything, but it might get you through. It might be necessary to retry your query after clicking Yes for the first time.
- Make sure that you are NOT using a proxy. Proxies are often badly configured, particularly when you try to perform HTTPS (secure) web connections. You can find the applicable proxy settings, if any, by choosing Tools > Internet Options from PoP's main menu, then going to the Connections tab, clicking on the LAN settings button, and making sure that no proxy is configured.
- Change the Google Scholar URL (if you are trying to perform a Google Scholar lookup, and not Microsoft Academic) to use plain HTTP (insecure) instead of HTTPS (secure): choose Tools > Preferences on the PoP main menu, go to the Google Scholar tab, and edit the Query URL field so it starts with http:// instead of https:// This won't work for Microsoft Academic --which always uses HTTPS-- and may not work much longer for Google Scholar, because Google is also transitioning to HTTPS-only.
- Upgrade your system to at least Windows 7 and at least Internet Explorer 11, and make sure that all "recommended" Windows Update updates have been applied.
To avoid exceeding the maximum acceptable Google Scholar request rate.
In February 2013 Google Scholar reduced the maximum number of results per page from 100 to 20. This means that Publish or Perish now has to retrieve up to 5 times as many result pages per query in order to show the full results.
- More page requests mean that Publish or Perish hits the maximum number of requests that Google Scholar allows per hour sooner.
- If the number of page requests exceeds the maximum that Google Scholar allows, your IP address will be temporarily blocked by Google Scholar. This block can last for up to 24 hours.
- To avoid hitting the maximum allowable request limit, Publish or Perish now uses an adaptive request rate limiter. This limits the number of requests that are sent to Google Scholar within a given period, both short-term (during the last 60 seconds) and medium term (during the last hour).
- To achieve the required reduction in requests, Publish or Perish delays subsequent requests for a variable amount of time (up to 1 minute). The higher the recent request rate, the longer the delays.
The net result is that queries will take longer than before. The alternative is being blocked by Google Scholar for up to 24 hours. We consider the relatively short delays during queries as the lesser evil, hence the adaptive rate limiter. If you perform queries with few results or only occasionally, then the request rate limiter will have little or no effect on the query time. In this case, the required delays are short or non-existent, and Publish or Perish will retrieve result pages as fast as it did in the past.
However, if you perform queries that yield many results (several hundred or more) or issue a number of queries in short succession, then the request rate limiter will insert progressively longer delays to keep the overall request rate within acceptable limits. If you want to avoid this, then the best remedy is to spread your queries over the day.
To use the adaptive request rate limiter, make sure that:
- You are using Publish or Perish version 4.0.12 or later (if not, then we strongly recommend that you upgrade to the latest release).
- The adaptive rate limiter is enabled and uses the recommended settings.
Not so; you can search for any name (or other words) regardless of the language.
Publish or Perish submits your query properly encoded to Google Scholar, so as long as Google Scholar has matching data, the information will be found. However, it can be that Google Scholar's coverage of non-English source material is less complete than that of English.
If you are looking for an author whose name contains accented letters, then it might help if you include several variations of the name, both with and without accents, and also with the accented letters missing. The reason for the latter is that some sources used by Google Scholar cannot handle accented letters and simply omit them.
For example, to search for someone with the surname Veríssimo (note the accent on the first 'i'), use the following names in the Author field:
Veríssimo OR Verissimo OR Verssimo
By using an OR query in the Author name field and specifying all names under which you published. For example, if you changed you name when you married, then use a query that includes both your maiden name and your married name.
You cannot do so directly.
Publish or Perish uses Google Scholar data or Microsoft Academic data and identifying self-citations requires numerous follow-up queries, potentially exceeding the acceptable number of Google Scholar and Microsoft Academic queries. For that reason, Publish or Perish restricts your queries to first-level queries only. If you want to exclude self-citations, you must identify them yourself and then exclude them from the Results list by clearing their check boxes.
Unfortunately, Google Scholar and Microsoft Academic don't seem to support complicated Boolean queries and do not have any systematic information on what they do support. From experience, you can conduct an "OR" query, but it does not seem to be possible to combine or exclude authors ("jj smith" AND NOT "j smith "). You might wish to run some experiments in the general citation search tab to see whether that delivers better results.
The following seem to work with the Author's name field:
- To perform an "and" search, enter multiple author names separated by AND
- To perform an "or" search, enter multiple author names separated by OR
You cannot do so directly.
Google Scholar does not have a bibliographic field listing affiliation in the same way as ISI does. Hence a search like the one you describe will not always give reliable results. You can try to search with your university name in the General Search All of the words field (for details see: General Search: Institutions), but this will match the name anywhere in the documents (not only as author affiliation) and for some universities is not comprehensive. Currently, we therefore cannot recommend this type of analyses with Google Scholar beyond very general curiosity driven experiments.
Yes, up to a point. Search for relevant keywords in either the All of the words or The phrase field (see helpfile for description of these fields). For Google Scholar you might want to tick Title words only if you think that the most relevant works will have the keywords in their title; Microsoft Academic by default only searches in the title and abstract.
The most cited results are (probably) the main publications.
Yes, up to a point. You can find the main authors (or at least the most cited ones) in both a subject area and in a specific journal.
In a subject area: Search for relevant keywords in either the All of the words or The phrase field (see helpfile for description of these fields). You might want to tick Title words only if you think that the most relevant works will have the keywords in their title; Microsoft Academic by default only searches in the title and abstract.
In a specific journal: Search for the relevant journal in the Journal title field. You may want to restrict your search to a certain period by using the Year of publication fields.
The most cited results belong to (probably) the main authors in the field or journal. You can also sort the results list on the Authors column; this groups papers by the same author together and may tell you at a glance who the most active authors are in a given area or journal.
Missing papers or references
Assuming that you really have published scholarly papers, there may be several reasons why Publish or Perish doesn't return any results for your name.
- You spelt your name incorrectly. Correct any typos and try again.
- You entered your given names in full instead of as initials. This may find some papers, but many publishers only list the author's initials and a full name search misses those papers. To be on the safe side, try using both full names and initials in a single query, like this (the "quotes" are highly recommended): "A Harzing" OR "Anne-Wil Harzing"
- Your papers are not available online, neither through your publishers nor through your own web pages. If that is the case, then Google Scholar and Microsoft Academic do not know about your papers.
- You published in a language other than English. Google Scholar's and Microsoft Academic's coverage are improving, but non-English publications still are underrepresented in the results.
Sorry, no. We do not personally maintain a database of academic publications.
Publish or Perish uses Google Scholar and Microsoft Academic data to calculate its citation metrics. Their processing is automatic (unlike ISI's or Scopus' that involves manual handling and checking, with the associated price tag) and hence occasional errors or omissions do occur.
This may be due to:
- Papers that are not (yet) available online. This includes many older papers.
- The nature of the publication: some books and other non-journal publications might not be accessible to Google Scholar or Microsoft Academic.
- Publishing in journals to which Google Scholar or Microsoft Academic has no access because of the journals publishers' policy.
Sorry, no. We do not personally maintain a database of academic publications.
As indicated elsewhere on the this website, Publish or Perish uses Google Scholar and Microsoft Academic data to calculate its citation metrics. Their processing is automatic (unlike ISI's or Scopus' that involves manual handling and checking, with the associated price tag) and hence occasional errors or omissions do occur.
This may be due to:
- Incorrect or sloppy referencing of your paper by others. Try to find the referencing works to see if this is the case.
- References in older journals or in journals that are not available online. Google Scholar only uses online information; if your paper or the references to it are not online, they will be omitted.
- References in journals to which Google Scholar or Microsoft Academic has no access because of the journals publishers' policy.
Publish or Perish uses the Google Scholar Advanced Search options. This is not the same as the standard Google Scholar search box. The search results might differ for one or more of the following reasons:
- A Google Scholar general search returns papers in which the search terms that you entered appear anywhere - as author, title, or even in the contents. In contrast, a Publish or Perish search is more specific and will only return papers that match in the fields that you specified: author names only in the author field, title words only in the title, etc.
- Perhaps Google Scholar did not classify your name correctly as an "author", but somewhere else (for example as part of the title - this is usually due to sloppy references to your article). A Google Scholar general search will still include the paper, but the more specific search that Publish or Perish uses will not if it does not find your name in the "Author" field.
For more details on this, please see Accuracy of the results.
Perhaps your academic field is not fully covered by Google Scholar and Microsoft Academic.
Publish or Perish uses Google Scholar or Microsoft Academic data to calculate its citation metrics. Although in general coverage of both these sources is more comprehensive than Scopus or the Web of Science, this might not be true for every individual academic. If you prefer to use Web of Science of Scopus data, refer to the linked pages for information on how to import data from these sources.
We do not personally maintain a database of academic publications.
Publish or Perish uses Google Scholar and Microsoft Academic data to calculate its citation metrics. You will therefore need to contact them to include your journal. Once they do, Publish or Perish will use the same data.
In the early days, Google Scholar provided complete records for authors and the publication source. However, since about 2012 both fields are regularly truncated, with part of the field replaced by dots […..]. We do not know why Google Scholar decided to introduce truncation. It might be related to the “space” available in these fields. Unfortunately it can make finding the right publication very frustrating, both in the Google Scholar interface and in Publish or Perish. For more details see: Google Scholar: Truncation
Workaround: Use Publish or Perish to generate a list of articles (including truncated entries) and save the results as BibTeX, EndNote, or RIS/Reference Manager (Select the Query, Right-click and click Save to File). Import this file into a new folder in Mendeley, right click and select ‘update details’. This completes most of the truncated entries. Please note that this is limited to entries where Mendeley can find the full entry and is thus more likely to work for traditional publications such as journal articles. [Thanks to Alex Harrison at the European Society of Endocrinology for this tip]
Publish or Perish uses Google Scholar and Microsoft Academic data and these data occasionally split what you know is a single paper into multiple entries. This is usually due to incorrect or sloppy referencing of your paper by others, which causes Google Scholar to believe that the referenced works are different. As of Publish or Perish release 3.0.3780 it is possible to merge duplicate results manually in the results list.
Publish or Perish uses Google Scholar and Microsoft Academic data and these data sources will typically consider different language editions of what you know as the same journal as separate journals. For example, English and French versions of a Canadian journal (or merely of different versions of the journal title) will typically be considered to be different. As of Publish or Perish release 3.0.3780 it is possible to merge duplicate results manually in the results list.
Other search and results issues
In general, this is rather difficult, because a lot depends on the accuracy with which your papers are referenced by others.
However, if you have separate web pages for each of your papers, then Google Scholar advises that you can add several meta tags to your pages to help Google's crawler to list your paper. In particular, they recommend using the following tags (replace the content="..." bits with your own information):
<meta name="citation_journal_title" content="Journal Name"> <meta name="citation_authors" content="Last Name1, First Name1; Last Name2, First Name2"> <meta name="citation_title" content="Article Title"> <meta name="citation_date" content="01/01/2007"> <meta name="citation_volume" content="10"> <meta name="citation_issue" content="1"> <meta name="citation_firstpage" content="1"> <meta name="citation_lastpage" content="15"> <meta name="citation_doi" content="10.1074/jbc.M309524200"> <meta name="citation_pdf_url" content="http://www.publishername.org/10/1/1.pdf"> <meta name="citation_abstract_html_url" content="http://www.publishername.org/cgi/content/abstract/10/1/1"> <meta name="citation_fulltext_html_url" content="http://www.publishername.org/cgi/content/full/10/1/1"> <meta name="dc.Contributor" content="Last Name1, First Name1"> <meta name="dc.Contributor" content="Last Name2, First Name2"> <meta name="dc.Title" content="Article Title"> <meta name="dc.Date" content="01/01/2007"> <meta name="citation_publisher" content="Publisher Name">
If you don't know what meta tags are, then this information is not for you.
This means that the Google Scholar response to your query contained no recognizable data. Possible causes include:
- The Google Scholar output format has changed.
- Your Internet connection does not work.
While we try to adapt as quickly as possible to changes in the Google Scholar output format, there may be a delay of a few days after Google Scholar introduces a new format.
Furthermore, even after we release a new version of the software, you must update your own copy of Publish or Perish to receive the benefit of the new software version. You can do so through the Publish or Perish web page, or by using the Help > Check for Updates command from the Publish or Perish main menu.
After updating the Publish or Perish software, retry the query using the Lookup Direct button (instead of Lookup). This retrieves fresh query data from Google Scholar, which might resolve the problem.
If nothing else helps, then please lodge an error report to Publish or Perish technical support as follows:
- Repeat the query that failed.
- Choose the Tools > Report Error command from the main menu.
This generates an error report (a plain text file) called PoPError.txt that you should attach to your email to the Publish and Perish support address. We need the information in the error report for an accurate diagnosis.
This error code appears when Google Scholar sends a CAPTCHA in response to a request and your system contains an out of date version of Internet Explorer. Solving the CAPTCHA requires a recent version of Internet Explorer (IE8 on Windows XP and IE11 on all later Windows versions). The Wine emulation of IE is insufficient for this and will also cause this error message.
You can do one of the following:
- On a real Windows system, run Windows Update to install the latest version of Internet Explorer (in fact, PoP will offer to start Windows Update for you); or
- Use a different data source within PoP (we support six different sources, most of which are free or require a free subscription key); or
- Wait 3-4 hours before resuming your queries; or
- Continue on a full Windows system if you are currently running on Wine. This can also be a virtual machine; we use VirtualBox on Linux and macOS (both iMacs and MacBooks) with Windows 7 inside.
This means that the Google Scholar response to your query contained no entries. Possible causes include:
- A query that did not match any papers. Try changing the query parameters.
- Your Internet connection does not work.
This means that the Google Scholar response to your query contained a refusal to accept further requests from your IP address. This is usually caused by an excessive number of prior queries. Google Scholar will normally lift the block after 24 hours.
In most cases, you can prevent this type of block by using Publish or Perish's adaptive request rate limiter. This limiter is enabled by default as of Publish or Perish release 4.0.12.
- If you are using an older version of Publish or Perish (before 4.0.12) then we strongly recommend that you upgrade to the latest release.
- If you are already using Publish or Perish 4.0.12 or later, then make sure that the adaptive rate limiter is enabled and uses the recommended settings.
If you are unlucky, it could be that your computer is located behind a web proxy that forwards your queries and those of your colleagues to Google Scholar. In that case, all those queries appear to come from a single system as far as Google Scholar is concerned, which may cause it to block further queries from any of you. Contact your local system administrator if you suspect that this might be the case.
Tip: As of Publish or Perish 4.0.15, you can enable Google CAPTCHA support in Publish or Perish by checking the Respond to verification requests option. When enabled, Publish or Perish will respond to Google's request for human identification and present the CAPTCHA image from Google. You can then type in the words shown in the image and submit them to Google. If you solved the CAPTCHA correctly, then Google will allow further access from your Publish or Perish session.
No; this is too difficult with the current results from Google Scholar. Here is what the Publish or Perish developer had to say about this when he investigated the issue in March 2009:
Hi Anne-Wil, I have looked into the weighted author contribution issues that you raised, and here are my findings. (a) The actual calculations are simple enough and not a limiting factor. (b) The trouble lies with reliably identifying and tracking individual authors in a set of results. Let me clarify point (b). In a typical set of Publish or Perish search results, the Authors field of each results item contains a semi-formatted list of author names. It is possible, up to a point, to split each author list into its separate author names. We already do so for the purpose of the Individual h-index, and also to provide an overview of papers with 1, 2, 3, etc. authors. For the Individual h-index this is sufficient, because each author receives the same weight (namely, 1/n if 'n' is the number of authors for that paper). However, reliably recognizing and tracking a given author, as would be required for any scheme that assigns unequal weights to authors based on their position in the authors list, is a different matter. The Google Scholar data contains a lot of noise (usually through no fault of Google, but simply the result of sloppy or inconsistent referencing by humans) that makes this harder than it appears. To give just one example: an author search for "a harzing" [sic] results at the moment [March 2009] in 158 papers, most of which appear to be (co-)authored by you. Looking at the results, your name appears as: A Harzing AK Harzing AW Harzing AWK Harzing AWIL Harzing ...but in some of the results it doesn't appear at all. Now you and I may know that all these variations refer to the same person (you), but this cannot be universally assumed: - For an author search, the search phrase "a harzing" might give a clue, but only if you are prepared to follow English naming conventions of one or more initials followed by a surname. For other cultural conventions, this might not be appropriate. - What if the author search phrase used several author names, like: "a harzing" OR "c kulik"? - For non-author searches, you don't even have this starting point. - For any searches, you might want to extract a list of all author names from the results, but then the matching process across the results set is even iffier -- perhaps not for semi-unique names such as Harzing, but certainly for the Smiths and Browns of this world. - And then there are completely garbled results, like this one from the same sample: Authors: AW Harzing, R Wal Title: van der (2008). A Google Scholar h-index for journals... This refers to the article you co-wrote with "R van der Wal", but no algorithm would be able to find this person in the Authors field. Therefore, to get this to work, we would have to implement some sort of user interface that allows the user to indicate which authors should be combined. This in itself is not rocket science, but it will take more development work to make it usable to the average user than we have available at the moment.
Situation: You have just done a search (any search) with specific start and end years, for example from 2000 to 2005. However, the results do not show "6 years active" as you expected, but "10 years active" (if the search is done in 2009). What's going on?
Answer: The search period (2000 to 2005 in the example) restricts the original publications. It does not restrict the citations.
Regardless of the start and end years in your query, the results will always show the citations until the present day, give or take a few weeks. And because Publish or Perish shows citation statistics, we must count all years from the start year until the present day.
Before you ask: No, Publish or Perish does not have control over this aspect of the results; it's Google Scholar that provides these data.
Publish or Perish stores a lot of files in the %APPDATA%\Publish or Perish folder on your computer. Some of these are essential, while others are merely useful.
You may find the following folders and files in the PoP data area:
- Cache folder
- Contains the raw, cached replies from the various data sources. They can be safely deleted (the Tools > Clear Cache command does that) but will incur some cost when earlier queries are repeated and may cause Google Scholar (for example) to throw more CAPTCHAs at you.
- Results6 folder
- Contains the parsed results, one .json file per query. Do not delete these, or you will lose your query results.
- Results3, Results5 folders
- If you still have these but are now using PoP 6.x exclusively, then you can delete those folders.
- Temp folder
- Files in this folder may be safely deleted once PoP has exited.
- Trash folder
- Contains backup copies of the previous query tree, plus the results of queries that have since been deleted, just like the Windows Recycle Bin. The Trash contents are (safely) trimmed by the Tools > Clear Garbage command. You can also delete them manually, but that will make previously deleted results unrecoverable.
Further information about PoP's backup regime can be found under "On-disk backup copies" in the Preferences: General dialog box.
Software installation issues
This occurs when you try to update the Publish or Perish software on Windows XP and later (including Vista and 7). The full error message is:
Error 740 while updating the software. The required operation requires elevation.
This is caused by an old version of the update software; it is not related to the Publish or Perish software itself. To resolve it, do the following.
- Close any running instances of the Publish or Perish software.
- Download the latest version of the software from the Publish or Perish page. This will result in a file called PoPSetup.exe on your computer.
- Run the PoPSetup.exe program that you just downloaded. This will update the Publish or Perish software on your computer to the latest version.
This procedure needs to be performed only once; later versions of the Publish or Perish updater no longer cause the error message.
This is a problem in Wine.
The DLL (sxs.dll) and function (CreateAssemblyCache, or a related function) in question are not available on all Windows platforms, so our installer very carefully:
- Checks for the presence of sxs.dll, then
- Checks for the availability of CreateAssemblyCache, and only then
- Calls that function.
What Wine does wrong is to provide the DLL and the function, but then bomb out when the function is called. What they should do instead is either not provide the function at all, or just return an error code when it's called.
Update: This problem was resolved in Wine release 1.1.20 when sxs.CreateAssemblyCache() was modified to return an error code (E_NOTIMPL) rather than causing a fatal error (fix courtesy of Kai Blin). If you experience this issue, then update your Wine installation to release 1.1.20 or later; this should resolve the problem. You can then use the normal Windows installer as documented on the Publish or Perish on GNU/Linux page.
